Specification of Letters Patent.

Patented June 5, 1906.

Application filed January 16. 1906.' Serial No. 296,419.

Toall whom it may concern Be it known that we, FERDINAND Frascn- BERGER, a subject of the Emperor of Austria, residing at Hoboken, and MEINRAD GEBHART, a citizen ofthe United States, residing at Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Windows, of which the following is a specification.

The present invention pertains to improvements in windows whereln the sashes are vertically slidable, and particularly-to that class in which the use of counterweigh'ts are dispensed with.

One of the objects of our invention is to provide a window having means whereby the sashes can be raised and lowered and held at rest by a frictional contact with the guidewa s inwhich they move at any desired point.

Xnother object is to render the sashes easily removable from the frame of the win dow for the purpose of effecting repairs without the necessity of removing any other parts of the window-frame.

A further object is to provide the sliding frames with French sashes -or easements swinging inward into the building for the urpose of allowing the cleaning of'gthe panes from the inside and outside, and thus avoiding the necessity for the clan erous practice of using the Window-sill there or.

With these and other objects inview our invention consists in the novel features of construction hereinafter set forth, and pointed out in the claims heretoappended.

In the accompanying drawin s similarreference-letters denote correspon ing parts.

, Figure 1 is a' front elevation of a window embodyin our invention, some parts of one of the sliding frames holding the easements being in section to show the bearing of the easement therein. Fi 2 is a similar view as Fig. 1, in which one of t e easements is swung open at one side, the window-frameibeing in vertical section to show the bearing of the sliding frames and the springs eflectinga frictional contact thereof with the frame ,of the window. Fi 3 is a cross-section on line a: w of Fi 1. Fig. 4 is a vertical section on line y y o Fi 5. Fig. 5 is an enlarged front elevation o the window, fpartly in vertical section, a portion thereo being broken away. Fi 6 is a cross-section on line .2 z of Fig. 1 on en arged scale. Fig. 7 is a perspective view of one of the easements, a portion thereof being broken away; and Figs. 8 and Q'are-detai s.

At both sides the. frame 1 has longitudinal guideways Zextending from the top to the sill of the window, and in each of the guideways two longitudinal metal rods 3"are arranged parallel to and behind each other said rods being rigidl fixed in the top and sill of the frame 1. rods 3 are metal bars 7, which have a double uided on said vertical 7 bend to form two longitudinal portions and a base portion, (see dotted lines, Figs. 1 and 2,) the longitudinal portions having eyes or cars 8 projecting laterallytherefrom, which and 5 is grooved in the outer surfaces of its side rails and bottom for its engagement with the metal bar 7, on which the same is mounted. The bottom portion of each metal bar 7 may be covered by a protection-plate 6, which is screwed or otherwise fixed to the sliding frame and which will prevent the latter from slipping off themetal frame 7. When thus mounted, the sliding frames 4 and 5 can be raised and lowered, together with the metal bars 7, on the vertical rods 3.

Between each of the frames 4 and 5 and the vertical rods 3 springs 9 are arranged at each side thereof, which springs are provided with rollers or wheels 10, adapted to roll 'on the ally against the sashes. As seen from Fig. 2, the upper and lower ends of the springs loosely rest against shoulders 11 formed on frames or parts connected therewith, the pro-- rods and which are arranged to press later- 5. The easements are adapted to swing inward within the buildin for the purposeof ermitting the cleaning 0% inside an outside. 0 this end a conical the panes from the hearing 14 is arranged in the bottom of each '4 and 5. Eat

sliding frame to receive a correspondinglyshaped pivot 15, projecting from the bottom of each casement. The upper pivots are formed by screw-headed pins 16, having a contracted portion 18, which engages a corresponding hole in the top rail of the sash 13,

the pins 16 Working in threaded bores 17, ar-

ranged in the u per rails of the slidingframes swinging sash is provided with a suitable locking mechanism. The easements can beremoved from the sliding frames "by unscrewing the upper pivots 16.

Instead of, as hitherto, cementing the pane with putty to the sashes, each swinging sash and engage a bore in the upper frame.

the inner surface of the sleeve a nose 25 pro.

jects inward, which is adapted to en age a helical groove 26, iormedin theenlarge inner end of the locking-bar.

Owing to the helical groove and the nose engaging therein, an involuntary unlocking of the sashes is prevented.

Having thus described the nature of our invention, what we claim, and desire to secure b Letters Patent, -is- 1 he combination Witha window frame,

of longitudinal guideways in the sides of the latter, vertical guide-rods in each guideway, vertically-sliding frames guided on said. rods, springs between the said sliding frames and guide-rods to effect a frictional contact with the latter and. horizontally-swim ing sashes in said sliding frames, substantia ly and for the purpose as specified.

2. The combination witha window-frame, of longitudinal guideways the sides of the latter, two vertical guide-rods in each guideway arranged parallel and behind each-other, double-bent bars uided on said rods, 'irames mounted on sai' bars and adapted to be raised and lowered, with the latter, springs between the said sliding frames and. guiderods to effect a frictional contact with the latter andhorizontally-swinging sashes in said sliding frames, substantially and for the purpose as specified. Y

3. The combination with a windowdraine, of longitudinal (guideways in the sides ofthe frame, tWo ui e-rods in each guideway arranged paral el and behind each other, doublebent bars, ears projecting laterally-from the latter and adapted to be in engagement with the. said guide-rods to permit said bars of slidin vertically on the latter, frames re-, mova ly mounted on said double-bent bars, means for connecting the latter with said frames, springs between the said slid'in frames and guide-rods to effect a fiictiona contact with the latter and horizontall swinging sashes in said sliding frames, su stantially and for the pix v ose as specified.

4-. The combination a wmdow-frame, of a guideway in each side of the frame, two vertical rods in each guideway arran par allel and behind each other, two don la-bent bars slidably mounted on the said guidenods,v

frames removably mounted on said bars, means connecting the latter with the said frames, springs located between the sides of the frames and the vertical bars, rollers or wheels borne upon the ends of said springs, the rollers orwheels 'bein adapted to roll u on the vertical rods an to 1 ress against to sides of the frames, and 'iorizon-ta-llyswin ing sashes in said frames, substantially and Eor the purpose as specified.

5: The combination with a window-frame, of a guideway in each side of the frame, two vertical rods in each guideway, verticallyslidi-ng frames guided on said bars, springs efiectinga hictionalcontact of the saidsliding frames. with the guide-rods, swinging sashes to swin horizontally in said frames, means 'permittmg a swin in action of the sashes and a removal of the latter from the frames, substantiallyandfor the purpose asspectlied In testimony whereof we affix our sigma tures in presence of two witnesses.
